I have the Elite Mini Economy Series DVR and I am looking to pop in a 2TB Hard Drive. The compatibility list has: Western Digital Caviar Green series WD20EADS. But I can only get my hands on to WESTERN DIGITAL Green 2TB WD20EARX.

Does anyone know if it will work? I’ve read that if the DVR firmware is not compatible It will potentially not overwrite the data on the hdd.

For hard drives 1TB and larger we recommend staying away from Green drives all together. We have found that they often cause issues with DVRs that are constantly recording. We only use SV (Surveillance Series) hard drives for hard drives of 1TB or larger now.

Typically with Green or Eco Friendly hard drives, they aren’t designed to read/write 24/7. They are generally designed to run at 7200rpm when reading/writing, but when they aren’t doing that they generally will drop down to 5400rpm to conserve power and prolong their life. Which in a computer is a good thing, but in a CCTV camera system the system is always reading/writing. You may get the drive to function, but it’s life expectancy will be extremely short due to it constantly reading/writing. I would highly recommend staying away from the Green drives, unless your recorded footage isn’t important to you!
